Answer:
9/5 miles in 1 hour
Step-by-step explanation:
As we are finding here the miles distance in 1 hour so we have to use here the formula which is
Rate = Distance / Time
Rate = 3/5 divided by 1/3
SO using third proportion rule we have to change the Numerator of second fraction with denominator and denominator with numerator and division sign will be change into Multiplication so this one will be
3/5 x 3/1
9/5 will be the answer
<span>75°
Since â–łABC is similar to â–łXYZ, that means that angle A equals angle X, angle B equals angle Y, and angle C equals angle Z. So let's look at the data we have.
Angle A measures 45° and angle C measures 60°. That means that angle B measures 180° - 45° - 60° = 75° since all triangles have 180° and we've been told the measurement of two of the angles. And since angle Y is equal to angle B (which we just calculated), that means that angle Y is also equal to 75°</span>

So first you want to find how much the second car gains on the first car in one hour.
Since the second car travels 65 kph, but the first travels 40, we can just subtract 40 from 65 to find how much faster the second car is than the first.
65 - 40 = 25
So the second car is 25 kph faster than the first.
Since the first car had a 2 hour head start, we first want to calculate how far away the first car got from the sign before the second car reached the sign.
So just 2 hours * 40 kph, which gives you 80 kilometers.
So now we know the second car has to gain 80 km on the first car in order to overtake it.
Since the second car gains 25 km per hour on the first car, we can just divide 80 by 25.
80 / 25 = 16/5, or in decimal form 3.2.
So the second car will overtake the first car in 3.2 hours, or 192 minutes, which is also 3 hours and 12 minutes.
