Final answer:
To find Bryce's unit rate in miles per hour, we form a proportion and find that he rides at a unit rate of 19 miles per hour. Often we are required to find the price or speed or other factors in the arithmetic problems. A concept that we very commonly come across in arithmetic as well as in practical life, is the unit rate.
Step-by-step explanation:
To determine Bryce's unit rate in miles per hour, we need to calculate how many miles he can ride in one hour. Since he rides 1/3 of a mile in 1/57 of an hour, we can set up a proportion to find the number of miles per hour:
1/3 mile : 1/57 hour = x miles : 1 hour
To solve for x, we can multiply both sides of the proportion by 57 to cancel out the denominator on the right side:
(1/3) * 57 = x
So, Bryce's unit rate is:
x = 57/3 = 19 miles per hour.
Unit rate is the ratio of two different units, with denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc. Arithmetic is probably the most basic and ancient branch of mathematics and is quite commonly used in our day-to-day life. This subject is all about the problems based on numerals and operations upon numerals. We do solve problems of arithmetic intentionally or unintentionally during our daily routine.
For example – While purchasing vegetables or fruits, in other dealings or in estimating speed of something etc.
