Answer:
3.86 hours equation km/70=h
Step-by-step explanation:
We know that the bus started 300 km away from Orlando, and now it is 30 km away from Orlando. 300-30=270
We also know that the bus is driving 70 km per hour
In order to find how long it has taken the bus to travel the 270 km you need to divide 270 by 70.
300-30=270
270 divided by 70= 3.86 hours
The equation would be km/70=h
The input values that would produce that output value, we set the output equal to the function's formula and solve for the input.
