Question

Two cars (Aand B) started from the same point at the same time in opposite directions. car a travelled a distance of 122 km in 5 hours . if the speed of the car B is 8.5m/s, what is the distance between them after 3 hours ?
​

Answer 1

Answer:

97.6km

Step-by-step explanation:

Converting speed of b .
8.5m/s.
8.5x18= 153.
153/5 = 30.6kmh.

Now we know that both cars started from same point and same time therefore now we have to find how much did in 3 hours.

hence  30.6x3 = 91.8 km
and speed of car a = 122/5 = 24.4 kmh.

therefore distance = 24.4x3 = 73.2km.

Distance between them in 3 hour = 24.4+73.2= 97.6
