Answer:

  • The speed is 160 km /h

Step-by-step explanation:

A driver spent 45minutes to cover a distance of 120km

Convert minutes to hour

  • 45 min = 45 /60 hr = 3/4 hr

Use the distance equation

  • d = ts

Find the speed

  • s = d/t

Substitute the distance and time value and find the value of speed

  • s = 120 / (3/4) = 120 * 4/3 = 160 km /h
