Question

If joe drives 30 mph 1/2 an hour and then 60 for 2 hours, then how far did he drive

Answer 1

If you mean 60 mph then it is 135 miles.

Answer 2

135 miles

Explanation:

∵ Distance = speed × Time,

Given,

Speed = 30 mph,

Time =
`(1)/(2)` hour,

Thus, distance =
`30* (1)/(2)` = 15 miles,

Now, speed = 60 mph,

time = 2 hours,

So, distance = 60 × 2= 120 miles,

Hence, the total distance covered = 15 miles + 120 miles = 135 miles.
