A car travels 65 km in 45 minutes what is the average speed of the car in km/h

nekit [7.7K]

So to begin your problem, you know that your car already has an average which is 65km/45 mins. The problem wants you to change this to km/hr. This means that you need to convert minutes to hours. A simple way to do this is by using fractions.
Set your problem up with fractions similar to this:
65km/45 mins x 60 mins/1 hr.
the whole point is to cancel out your minutes, and leave the hours as your new unit for the denominator
65km/45 x 60/1 hr.
now you want to reduce (I divided the first fraction by 5)
13km/9 x 60/1 hr.
780km/9hrs.
That would be your answer. If someone can double check my math that would be fantastic.

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did

Tanya [424]

Answer:

$r=0.05$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

A is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=3\ years\\ P=\$3,000\\I=\$450\\r=?$

substitute in the formula above

$450=3,000(3r)$

solve for r

$450=9,000(r)$

$r=450/9,000$

$r=0.05$
