Alex is driving at a constant rate of 50 miles per hour. how far will alex travel in: 2 hours, 4.3 hours, 20 minutes?

50 * 2 = 100

in 2 hours Alex will travel 100 miles

50 * 4.3 = 215

in 4.3 hours Alex will travel 215 miles

50 * 20/60 =  16 2/3 miles  {convert minutes to hours  by dividing by 60}

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
