Question

Batman and Robin both leave the batcave at the same time going in the same direction. Batman is driving the batmobile at 70 mph. Robin is following on his motorcycle at 50 mph. How long will it take for them to be 80 miles apart?

Answer 1

Batman and Robin will be 80 miles apart after 4 hours.

Step-by-step explanation:

To find how long it will take for Batman and Robin to be 80 miles apart, we can use the formula:

Distance = Speed x Time

Since Batman and Robin are going in the same direction, we can subtract their speeds to find their relative speed:

Relative Speed = Batman's Speed - Robin's Speed

So, the relative speed is 70 mph - 50 mph = 20 mph.

To find the time it will take for them to be 80 miles apart, divide the distance by the relative speed:

Time = Distance / Relative Speed

Time = 80 miles / 20 mph = 4 hours.

Therefore, it will take Batman and Robin 4 hours to be 80 miles apart.
