Todd and Kristin each drove across the state. Todd drove 375 miles in 5 hours; Kristin drove for 6 hours. If they traveled at the same speed, how many more miles did Kristin drive than Todd?

75 miles

Step-by-step explanation:

Since they drove at the same speed, the first 5 hours that Todd and Kristin drove are the same. So, Kristin drives 1 additional hour. Since Todd drives 375miles/5hours, or 75mph, Kristin drives 75 additional miles.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

40 x 50 = 2000
