Question 1 Direct and Inverse Proportions Exercise 12C

A car is travelling at a uniform speed of 75 km/hr. How much distance will it

cover in 20 minutes?

a) 25km

b) 15km

c) 30km

d) 20km

Answer:

By using the formula Speed= Distance/Time

Let us consider the distance be x km

Time= 20/60hr = 1/3 hr

S = D/T

75 = x/(1/3)

x= 75 × 1/3

x= 25

∴ 25km is required.
