- $18$ m/s
- $22.5$ m/s
- $25$ m/s
- $27$ m/s
Show answer and solution
Correct answer: C. $25$ m/s
Multiply km/hr by $\dfrac{5}{18}$: $90 \times \dfrac{5}{18} = 25$ m/s.

A car covers $360$ km in $4$ hours. Find its average speed.
- $60$ km/hr
- $80$ km/hr
- $90$ km/hr
- $100$ km/hr
Show answer and solution
Correct answer: C. $90$ km/hr
Speed $= \dfrac{\text{Distance}}{\text{Time}} = \dfrac{360}{4} = 90$ km/hr.
A man travels the first half of a journey at $30$ km/hr and the second half at $60$ km/hr. Find his average speed for the whole journey.
- $35$ km/hr
- $40$ km/hr
- $45$ km/hr
- $50$ km/hr
Show answer and solution
Correct answer: B. $40$ km/hr
For equal distances, average speed is the harmonic mean: $\dfrac{2xy}{x+y} = \dfrac{2 \times 30 \times 60}{90} = \dfrac{3600}{90} = 40$ km/hr.
Not the arithmetic mean $(30 + 60)/2 = 45$ — that holds for equal *times*, not equal *distances*.
