Answer:
50 miles per hour
Step-by-step explanation:
Here,
Time= 8 hours
Distance=400 miles
The speed is calculated by dividing the distance by time.
So,
Average Speed=Distance/Time
= 400/5
=50 miles per hour
Answer:
number of cars: x = 30
number of vans: x = 14
Step-by-step explanation:
For 44 cars, the amount they collected would have been 44*5 = 220 dollars, but the total was 262 dollars, which is 42 dollars more.
Each van costs $3 more than each car. $42 "extra", divided by $3 "extra" for each van, means 42/3 = 14 vans. And that leaves 30 cars.
check: 30(5)+14(8) = 150+112 = 262
or, using algebra...
let x = the number of cars
then 44-x = number of vans
Step-by-step explanation:
(8y)2=16y
(8y)²=64y²
