Question

A car travels at a speed of 50km/h in the first 30 minutes and 100km/h in the next 30 minutes. What is the total distance covered by the car?​

Answer 1

Answer:

75 km

Explanation:

$v_{1}$ = 50 kmph

$t_{1}$ = 30 min = 0.5 h

$v_{2}$ = 100 kmph

$t_{2}$  = 30 min  = 0.5 h

Distance travelled with speed $v_{1}$ = ($v_{1}$)($t_{1$) = (50)x(0.5) = 25 km = $x_{1}$

Distance travelled with speed $v_{2}$ = ($v_{2}$)($t_{2}$) = (100)x(0.5) = 50 km = $x_{2}$

∴ Total Distance = $x_{1} + x_{2} = 25 km + 50 km = 75 km$
