Answer:

2.5 hours

Skills needed: Speed, distance, time problems

Explanation:

1) We are given speed and distance, and have to find out the the time (in hours).

- In terms of units, everything is matched up (Since distance and speed use kilometers, and speed and time use hours).

- Time is always the distance you travelled (how far) divided by how fast you travelled (the rate/speed)

---> We can use the formula for time:
t=\frac{d}r

t= time

d=distance

r=rate/speed

2) Now, let's plug in for distance and rate.

--->
t=(7.5)/(3) = 2.5

2.5 hours is the answer.
