The first speed limits for cars were two miles per hour in a city and four miles per in the open country. How long would it take for a motorist to travel 15 miles assuming that he had to travel in the city. Please show work.

Divide 15 by 2.

distance = rate x time.

watch units.

Are you both telling me to do the same thing.

How long would it take the same motorist to travel 1,500 miles if he avoided the cities?

To calculate the time it would take for a motorist to travel 15 miles at a speed limit of 2 miles per hour in the city, you can use the formula:

Time = Distance / Speed

In this case, the distance is 15 miles and the speed is 2 miles per hour. Plugging these values into the formula:

Time = 15 miles / 2 miles per hour

Time = 7.5 hours

Therefore, it would take the motorist approximately 7.5 hours to travel 15 miles at a speed limit of 2 miles per hour.

Note: This calculation assumes that the motorist is traveling at a constant speed of 2 miles per hour throughout the entire journey. In real-life scenarios, it's common for motorists to travel at varying speeds, depending on traffic conditions and other factors.
