It took kris 14 hours to drive to san francisco. he drove 75 miles an hour. he took a 2 hour break in las vegas. how many miles did kris drive?

900 miles

Step-by-step explanation:

Given:

Total time taken by Kris is 14 hours.

Speed of Kris is, Speed = 75 mph

Time spent while taking a break is 2 hours.

So, time Kris drove his vehicle is given as the difference of total time and time spent in break. Therefore,

Actual time of driving = 14 - 2 = 12 hours.

Now, distance traveled is given as the product of speed and time of driving.

∴ Distance = Speed Time

  Distance =

Therefore, Kris drove 900 miles.

1010: 3030

is it i think

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
