Question

Pogba leaves paris by car at 08:00. he completed the first 30km at 90 km/h. he then stops at a petrol for 3 minutes before travelling the final 32km to versailles at 96 km/h. at what time does pogba arrive in versailles?

Answer 1

Pogba arrives in Versailles at 08:43

Step-by-step explanation:

They complete the first 30 km at 90 km/h

Now using the equation,

speed = distance/time

or,

v = d/t

to find time, we get,

t = d/v

so,

for the first 30 km, d= 30 km, v = 90 km/h

t = 30/90 kmh/km

t = 1/3 h

1/3 h is 20 minutes

so it takes 20 minutes.

Then they stop for 3 minutes at the gas station

Finally, they travel the final 32 km at 96 km/h

This corresponds to a time,

t = d/v

here d = 32 km, v = 96 km/h

t = 32/96

t = 1/3 h

t = 20 minutes

or again,

it takes 20 minutes

In total, we sum these times, to get the total time,

T = 20 minutes + 3 minutes + 20 minutes

T = 43 minutes

Now,

They leave at 08:00, and they arrive 43 minutes later

hence at 08:43
