A car and a bus set out at 2 p.M. From the same point, headed in the same direction. The speed of the car is 30mph slower than t
Blizzard [7]

Answer:

Car = 10 miles/hour

Bus = 20 miles/hour

Step-by-step explanation:

Here,

Let, the value of the speed of the bus = X

the value of the speed of the car = 2X - 30 (As the speed of the car is 30mph slower than twice)

According to the question,

2X - 20 = 2*(2x-30)

or, 2X - 20 = 4X-60

or, 2X = 40

x = 20

Therefore, the speed of the bus, x = 20 miles/hour

So, the speed of the car is (2*20-30) mph = (40 - 30) mph = 10 miles/hour.
