Time and Distance Practice Test 3 with solutions

Distance covered by man = 6 km
Time = 45 minutes = $\frac{45}{60}$ = $\frac{3}{4}$ hrs
Speed = $\frac{6}{\frac{3}{4}}$ = $6\times \frac{4}{3}$ = 8 km/hr
According to the statement,
$\frac{1}{2}\left(6\right)$ = $\frac{2}{3}\left(\frac{3}{4}\right)$ = $\frac{1}{2}$
3 = $\frac{1}{2}$
The remaining distance = 6 - 3 = 3 kms
Remaining time to cover the distance
= $\frac{3}{4}-\frac{1}{2}$ = $\frac{3-2}{4}$
= $\frac{1}{4}$ hrs
Speed = $\frac{\mathrm{Distance}}{\mathrm{Time}}$ = $\frac{3}{\frac{1}{4}}$ = 3 × 4
= 12 kms/hr.
