Answer:
294 miles
Step-by-step explanation:
using the relationship between distance / speed / time
distance = speed × time
calculating speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{126}{3}[/tex] = 42 mph
Then travelling at this speed for 7 hours
distance = 42 × 7 = 294 miles
If the car travels for 126 miles in 3 hours, you want to find out how much miles it can go for in 1 hour.
126/3 = ?/1
To find ? , you need to divide 126 by 3, which equals 42. So 42 miles PER HOUR.
Now, you want to find how many miles in 7 hours. So..
42/1 = ?/7 You need to do 42 x 7. That is 294.
YOUR ANSWER IS 294!!!!
