Answer 1

Answer: 0. 625 hour

Step-by-step explanation:

Given;

distance = 2 1/2 mile= 5/2 mile

speed = 4mile/hr

speed = distance /time

time = distance/speed

=5/2 / 4

= 5/2 × 1/4

=5/8

=0. 625 hour

we can convert to minute by simply multiplying by 60

Time taken (in minute) = 0. 625 × 60 = 38minutes
