A scooter travels 10 miles per hour faster than an electric bicycle. The scooter traveled for 3 hours, and the bicycle traveled
5 1/2 hours. Altogether, the scooter and bicycle traveled no more than 285 miles. Find the maximum speed of each.
1 answer:
Answer:
Bicycle: 30 miles/hour
Scooter: 40 miles/hour
Step-by-step explanation:
Let the speed of the bicycle be s,
Then the speed of the scooter is:
s + 10
Distance = speed × time
Distances covered:
Bicycle: (s)(5½) = 5.5s
Scooter: (s + 10)(3) = 3s + 30
Total:
5.5s + 3s + 30
8.5s + 30
8.5s + 30《285
8.5s《255
s《30
s + 10《40
