Answer 1

Answer: Yes

Explanation:

Given

Once around park measures 420 yards

Todd needs to complete 5 miles

He runs 30 times during the week

We know,
`1\ mile=1760\ yards`

for 30 rounds, distance is

`\Rightarrow 30* 420=12,600\ \text{yards}`

In miles, it is

`\Rightarrow 12,600\equiv (12,600)/(1760)\\\Rightarrow 7.159\approx 7.16\ \text{miles}`

As he runs more than the target. Therefore, he completed his target of 5 miles.
