Mike and jamal are 9 miles apart, and are planning to meet up. mike is walking at an average speed of 3 miles per hour to meet jamal. jamal is driving at an average speed of 25 miles per hour to meet mike. which equation can be used to find t, the time it takes for mike and jamal to meet? a.25t – 3t = 0 b.25t – 3t = 9 c.25t + 3t = 1 d.25t + 3t = 9

Oprion D. 25t + 3t = 9

Step-by-step explanation:

Mike and Jamal are 9 miles apart, and they are planning to meet up.

Let Mike and Jamal met after (t) hours.

Speed of Mike was 3 miles per hour

So distance covered by Mike in 't' hours = 3t miles

Average speed of Jamal is 25 miles per hour.

so distance covered by Jamal will be = 25t miles

So distance covered by James and Mike = 3t + 25t

This distance is 9 miles, so equation to calculate the time will be  3t + 25t = 9

Option D. 25t + 3t = 9 is the answer.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
