A car is traveling at 70 miles per hour on the highway. Which equation could you use to calculate the distance, d, the car trave
ls after any given amount of time, t?
1 answer:
Answer:
d = 70t
Step-by-step explanation:
The units of speed tell you how to write the equation.
speed = miles/hour
Multiplying by hours gives ...
speed · hours = miles
Using the required variables and the given speed, you have ...
70t = d . . . . . time in hours, distance in miles

D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
