What is the ratio of miles run to miles biked if the total distance is 8.25 miles when 5.5 miles are biked?

Back

The ratio is 5.5 miles biked to 2.75 miles run, which simplifies to 2:1.

Front

How do you calculate the total distance exercised if you know the distance biked and the ratio of biking to running?

Back

Use the ratio to find the distance run based on the distance biked.

Front

What expression equals 74 when x = 10, y = 8, and z = 12?

Back

x + 5y + 2z = 10 + 5(8) + 2(12) = 74.

Front

What is the relationship between distances biked and distances run if the distances biked are twice as far as the distances run?

Back

If the distances biked are twice as far, then for every mile run, two miles are biked.

Front

How do you find the speed of a jet if it travels 420 miles in 2 hours?

Back

Speed = Distance ÷ Time = 420 miles ÷ 2 hours = 210 mph.

Front

If a jet travels at 210 mph, how far can it travel in 13 hours?

Back

Distance = Speed × Time = 210 mph × 13 hours = 2,730 miles.

Front

What is the formula to find the total cost of items if you have a budget and fixed costs?
