Question

A jet flew to Las Vegas and back. On the trip there, it flew 260 km/h, and on the return trip, it went 156 km/h. How long did the trip there take if the return trip took ten hours?

a) 5 hours
b) 6 hours
c) 7 hours
d) 8 hours

Answer 1

The trip to Las Vegas took 6 hours.

Step-by-step explanation:

To find the time it took for the trip to Las Vegas, we need to use the formula:

time = distance / speed

On the return trip, the speed was 156 km/h and the time was ten hours. Therefore, the distance on the return trip can be found by multiplying the speed and time: 156 km/h * 10 h = 1560 km. Since the distance for the round trip is the same, the distance on the trip to Las Vegas is also 1560 km. To find the time on the trip to Las Vegas, divide the distance by the speed: 1560 km / 260 km/h = 6 hours.

Therefore, the trip to Las Vegas took 6 hours.
