Answer: they will meet after 3 hours.
Step-by-step explanation:
Let t represent the number of hours it will take them to meet.
A walker and a cyclist are 45 miles apart. If they move towards each other, in t hours, they would have covered a total of 45 miles
Distance = speed × time
They move towards each other with speeds of 5 mph and 10 mph respectively. It means that the distance covered by the walker in t hours is 5 × t = 5t
Also, the distance covered by the cyclist in t hours is 10 × t = 10t
Since the total distance covered us 45 miles, then
5t + 10t = 45
15t = 45
t = 45/15
t = 3 hours
Brazil population: 1.907×
Mexico population 1.123×
To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:
The 's would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.
1.907 - 1.123= 0.784
Brazil's population is 0.784× larger than Mexico.
