Answer:

The hours it takes Elena to meet Jada = 4 hours

Step-by-step explanation:

The distance between Elena and Jada = 32 miles

The speed with which Elena runs = 6 miles per hour

The speed with which Jada walks = 2 miles per hour

Let t, represent the time it takes until Elena and Jada meets, we have;

Distance = Speed × Time

The total distance covered by both Elena and Jada before they meet = The distance between them = 32 miles

The distance covered by Elena before meeting Jada = Elena's speed × The time that elapsed for them to meet

∴ The distance covered by Elena before meeting Jada = 6 mph × t

The distance covered by Jada before meeting Elena = Jada's speed × The time that elapsed for them to meet

∴ The distance covered by Jada before meeting Elena = 2 mph × t

The total distance covered by both Elena and Jada before they meet = The distance covered by Elena before meeting Jada + The distance covered by Jada before meeting Elena = 32 miles

∴ The total distance covered by both Elena and Jada before they meet = 6 mph × t + 2 mph × t = 32 miles

t × (6 mph + 2 mph) = 32 miles

t × 8 mph = t × 8 miles/hour = 32 miles

t = 32 miles/(8 miles/hour) = 4 hours

The time it takes until Elena and Jada meets = t = 4 hours
