Troy rides his bike for 7 hours and 30 minutes for 20 kilometers. What is his speed in miles per hour

1.65698933mph or 1.66

Step-by-step explanation:

20 kilometers divided by 7.5 hours is two and two-thirds kilometers per hour and once you convert the kilometers to miles you get 1.65698933 miles per hour. You can round it if you want some math teachers I have had didn't want me to round so I gave you both options.

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
